HP/UHP Spring-Loaded Regulator

Description

HP (High Purity) and UHP (Ultra High Purity) products are for service where the product must be kept free of contamination. The design is kept simple to minimise “dead” areas where contaminants might collect. Elastomers are not used and polymers are carefully selected for suitability. UHP uses the same design as HP but the parts are machined to a better surface finish to improve cleanliness. The valve is assembled in a clean room and is Helium leak tested by mass spectrometer. HP/UHP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. We offer a range of spring-loaded regulators that provide a flow of gas at controlled pressure. The outlet pressure is set by turning the control knob. The process fluid is isolated from the spring compartment by a metal diaphragm. The range of outlet pressure is set by the diameter of the diaphragm and the strength of the spring. The outlet pressure is substantially unaffected by flow rate but it does drop slightly as the inlet pressure is increased. A back pressure variant is available. This controls the inlet pressure by venting pressure to the outlet if the inlet pressure exceeds the set value.

• Final assembly and testing is carried out under class 10 conditions.

• Each valve is tested for leakage using a mass spectrometer.

• Leak rate is less than 10-9 mbar l/s of Helium, inboard, outboard and across seat.

• No lubrication is used in the flow path and the seat materials are chosen for minimal gas absorption.

HP/UHP Diaphragm Stop Valves

Description

HP (High Purity) and UHP (Ultra High Purity) products are for service where the product must be kept free of contamination. The design is kept simple to minimise “dead” areas where contaminants might collect. Elastomers and polymers are carefully selected for suitability. UHP uses a similar design to HP but the parts are machined to a better surface finish to improve cleanliness. The valve is assembled in a clean room and is Helium leak tested by mass spectrometer. HP/UHP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. We offer a range of stop valves in which a non-tied diaphragm isolates the operating mechanism from the process fluids. The HP/UHP 3600 series is operated by a quarter turn lever or a pneumatic actuator which may be normally closed or normally open.

Construction Build Standards (UHP only)

• The diaphragm is of one-piece non-welded construction for greater integrity and improved fatigue life. It acts directly on the seat to close the valve to minimise dead space and wetted area.

• The valve seat is mechanically supported and retained to minimise deformation under load and seat lift under reverse flow conditions.

• To prevent the shedding of particulate contamination, there are no sliding, rotating or rubbing components in the flow path.

HP Stop Valves Sealed Spindle

Description

HP (High Purity) products are for service where the product must be kept free of contamination. The design is kept simple to minimise “dead” areas where contaminants might collect. Elastomers are not used and polymers are carefully selected for suitability. HP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. We offer a range of stop valves in which the metal valve spindle seats directly on a seating face in the valve body. O-rings with back-up rings prevent leakage along the spindle. HP2200 valves have a partially balanced spindle to reduce the load applied by the process pressure. This means that handwheel torque is low even at the maximum operating pressure of the valve and a relatively small actuator can be used. Pneumatically actuated variants are available. Some variants of these valves have passed adiabatic shock tests at the independent test houses BAM and CTE to qualify them for use with Oxygen.


• Body: Stainless Steel, Monel or Brass • Valve: Stainless Steel or Brass

• O rings: Viton or EPDM • Back up rings: PTFE or Nylon




• The control knob for HP2000 and 2100 is available in metal or plastic in two styles.

UHP Bellows Stop Valve

Description

UHP (Ultra High Purity) products are for service where the product must be kept free of contamination. Elastomers and polymers are carefully selected for suitability. Parts are machined to a high surface finish to improve cleanliness. The valve is assembled in a clean room and is Helium leak tested by mass spectrometer. UHP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. CFASV is an actuated stop valve in which a long stroke bellows isolates the operating mechanism from the process fluids. The valve is sealed by a polymer seat. CFASV is intended for vacuum purging of empty gas cylinders. The valve can withstand the rated pressure of a full cylinder on the inlet but will not open unless the inlet pressure is below a safe value. To prevent the shedding of particulate contamination, there are no sliding, rotating or rubbing components in the flow path. A test port is provided to detect and contain leakage across the bellows.

Build Standards


• Ra 10 to 15 micro inch finish on wetted surfaces. • Final assembly and testing is carried out under

class 10 conditions. • No lubrication is used in the flow path and the seat

materials are chosen for minimal gas absorption.


• Leak rate is less than 10-7 mbar l/s of Helium, across seat, less than 10-8 mbar l/s of Helium, outboard, less than 10-9 mbar l/s of Helium, inboard.

UHP uses a similar design to HP but the parts are machined to a better surface finish to improve cleanliness. The valve is assembled in a clean room and is Helium leak tested by mass spectrometer. HP/UHP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. We offer a range of spring-loaded, non-return or check valves. They are suitable for use with gases or liquids to prevent reverse flow in high-pressure lines. The valves are sealed by an elastomer O ring. The main closing force is provided by the process pressure. The spring ensures that the valve will close at any orientation. The opening (cracking) pressure can be selected by specifying the strength of the closing spring. The internal design of the valve ensures that there is minimal restriction to flow.

UHP Relief Valve

Description

UHP (Ultra High Purity) products are for service where the product must be kept free of contamination. Elastomers and polymers are carefully selected for suitability. Parts are machined to a high surface finish to improve cleanliness. The valve is assembled in a clean room and is Helium leak tested by mass spectrometer. UHP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. We offer a range of differential relief valves. The valve is operated by an internal piston or diaphragm that is larger than the flow area. The process pressure acts on the difference in these areas (hence “differential”). This means that the spring can be small for high pressures. It also means the valve snaps open to full bore because as soon as the valve starts to open the process pressure acts on the full piston area. Each valve is adjustable within a range of pressures. The range depends on the size of the piston or diaphragm and the strength of the spring.

UHP Vacuum Generator

Description

UHP (Ultra High Purity) products are for service where the product must be kept free of contamination. Elastomers and polymers are carefully selected for suitability. Parts are machined to a high surface finish to improve cleanliness. The valve is assembled in a clean room and is Helium leak tested by mass spectrometer. UHP products may be used on reactive, corrosive and/or toxic products. Special materials are available for resistance to particularly aggressive chemicals. The UHP30 vacuum generator uses an ejector mechanism in which a flow of gas creates a vacuum. There are no seals and no moving parts. The body is machined from a single part so there are no leak paths. The vacuum generator is rated to withstand the rated pressure of a full gas cylinder.

Options Please contact us for details Build Standards • Ports: alternative port configurations can be supplied

including additional ports for gauges and relief valves.


• Certification: variants are available approved for use with Oxygen or for ATEX service.





Ordering Information Please supply the following information when ordering Standard Materials Alternative materials can be
